•Case Study: Continuous Simulation Of A Minnehaha Creek Watershed
Utilizing an existing XP-SWMM model created for the Minnehaha Creek Watershed District (MCWD) Hydrologic/Hydraulic and Pollutant loading study (see case study), a 55-year continuous simulation was completed. Three conditions were modeled: existing landuse, future land-use, and a wetland restoration scenario.
Model features allowing simulation of Minnesota's changing seasons, and critical for a good calibration, during the period-of-record run included infiltration and snowmelt simulation. Preparation for the run required assemblage of 55-years of precipitation (rain and snowfall), temperature records and base flow data. Precipitation data was compiled using the Thiessen Polygon method. Base flows, developed using Darcy's Law, were developed for the upper watershed streams to simulate a groundwater inflow. The flows were entered in the form of a user-defined inflow hydrograph that faded out during the winter and reemerged during the spring and summer months. The hydrology used Green-Ampt methodology.
